• Surge current capacity: 250 A minimum
• Energy absorption: 2.3 J
• Package form factor: 1210 (3225 Metric) surface mount
• Number of circuits: 1
• Mounting technology: Surface Mount, MLCV

The EPCOS - TDK Electronics B72530V0400K062 meets all specified electrical and mechanical parameters, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The EPCOS - TDK Electronics B72530V0400K062 is a direct substitute for the obsolete Würth Elektronik 82553400. Both components share identical electrical specifications, package geometry, and regulatory compliance status. The substitute maintains ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between these parts is determined by procurement availability and supply chain requirements, as electrical and mechanical performance are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the EPCOS B72530V0400K062 be used as a direct replacement for the Würth Elektronik 82553400?

A: Yes. Both components have identical varistor voltage ratings (68 V nominal), surge current capacity (250 A), energy absorption (2.3 J), and 1210 (3225 Metric) surface mount package specifications. Electrical performance and physical form factor are equivalent.

Q: Are there any differences in regulatory compliance between these parts?

A: No. Both components are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level and tariff classification are identical.

Q: What is the acceptable varistor voltage range for substitution?

A: The varistor voltage must fall within the range of 61.2 V (minimum) to 74.8 V (maximum). Both the original and substitute parts meet this specification at 68 V nominal.

Q: Does the packaging format differ between these components?

A: No. Both parts use identical 1210 (3225 Metric) surface mount MLCV package specifications. PCB layout and assembly processes remain unchanged.

Q: Why is the original Würth Elektronik part listed as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The EPCOS - TDK Electronics equivalent provides functional continuity for designs requiring 68 V, 250 A varistor protection in 1210 package format.
